Abstract

L'invention concerne un procédé de traitement dentaire. Dans ce procédé, une dent d'un patient est extraite et préparée pour créer une pièce radiculaire. Un canal radiculaire dans la dent extraite est préparé et traité. Un montant d'une butée est ajusté dans le canal radiculaire pour fixer la partie radiculaire à la butée. La butée ayant la partie radiculaire est fixée à un implant dentaire. Le fait que la pièce radiculaire soit fixée à la butée permet à un tissu conjonctif périodontique de maintenir l'os de mâchoire associé à la dent extraite, sans perte de tissu dur significative.
